Sales Audit Service

As part of our Sales Auditing Services, we provide a comprehensive evaluation of your sales transactions via your sales channels. We conduct a two-step evaluation of each ticket to determine whether the appropriate tariffs have been applied and the tariff conditions are met. As part of this process, we check all tariffs, fees and commissions for each ticket. In this way, we ensure that all information and amounts are shown correctly. Afterwards we create Agency Debit / Credit Memos via BSPLink, Memo Manager or directly. In the event of a dispute, we will take care of the matter so that you receive your money as soon as possible.

For this we offer the perfect solution:

  • Fare, Tax, Commission Audit
  • Creation of Agency Debit / Credit Memos
  • Dispute resolution (Dispute Process)

Tax Maintenance Service

Virtually every airport in the world has its own fee model, with different charges in each country. Keeping track of what is invoiced where and how is a Sisyphean task – which we are happy to handle for you. We initially record all relevant taxes (TFCs) based on RATD or TTBS data and continuously maintain them. Nothing stands in the way of a smooth billing process.
